HEEL-MAKING MA CHlNE- SPECIFICATION forming part of Letters Patent No.443,908, dated December 30, 1890.

Application filed August 11, 1890. Serial No. 361,657. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. FAHNLEY, a citizen of the United States,and a resident of Lynn, in the county of Essex andState ofMassachusetts, have invented new and useful Improvements in Heel-MakingMachines, of which the following, taken in connection with theaccompanying drawings,isa specification.

This invention relates to improvements in' heel-making machines, and itis carried out as follows, reference being had to accompanyin gdrawings, wherein Figure 1 represents afront elevation of the machine,and Fig. 2 represents a side elevation of it as seen from X in Fig. 1.Fig. 3 represents an enlarged detail section on the line Y Y in Fig. 1,showing the pivoted lever for carrying the cutter-block and heel-nailingdevice. Fig. 4 represents a detail sectional view of thecutter-block-holding device. Fig. 5 represents a detail longitudinalsection of the heel-die and die-carrier. Fig. 6 represents an enlargedlongitudinal section of the heel-nailing device. Fig. 7 represents a detail plan view of the perforated nail-loader. Fig. 8 represents a planview of the perforated loader-gate; and Fig. 9 represents an enlargedsection on the line Z Z in Fig. 1, showing the spring locking device forthe loader. I

Similar letters refer to similar parts wherever they occur on thediiferent parts of the drawings.

In the drawings, A is the frame or standard, in bearings in which isjournaled the drivingshaft B, provided with fast and loose pulleys Z)b,as shown in Fig. 2. A rotary motion is imparted to the shaft B bymeans of beltpower applied to its pulley Z) in the usual manner.

On the shaft B is secured a pinion B, the teeth of which mesh in theteeth of the gearwheel 0, loosely journaled on the shaft 0. A rotarymotion is imparted to the shaft 0 from the gear-wheel C by means of anywellknown clutch mechanism operated by the depression of thetreadle-lever D, pivoted at d and normally held in inoperative positionby means of a spring D.

I wish to state that I do not desire to confine myself to the use of anyparticular clutch mechanism, as any of 'the well-known forms may beused, by means of which a complete revolution is imparted to the shaft Oby the depression of the treadle-lever D without departing from theessenceof my invention.

To the forward end of the shaft 0 is at tached a crank-pin c, journaledin a block 6, adapted to move in'a horizontal slot E in the lower end ofthe die-carrier E, which is thus made vertically movable in guides A Aand A A secured to or forming parts of the frame or standard A. On theupper end of the die-carrier E is supported the heel-die E, which issecured in place on the said carrier, preferably, by means of lateralpressurescrews 6 e going through the sides of the upper portions of thecarrier E, as shown in Figs. 1 and 2. A vertical np-and-down movement isby the means imparted to the heel-die and its carrier for every time thetreadle-lever D is depressed. lVithin the heel-die E is arranged thevertically-adjustable nail-clinching and heel-regulating block f, havinga downwardly-projecting shank f fitting into a vertical recess in theupper end of the spindle F, which is guided in bearing F. and E in thedie-carrier E, as shown in Fig. 1.

The lower end ofthe spindle F is screwthreaded and made to pass looselythrough the bearing E Above said bearing E is arranged upon thescrew-threaded portion of the spindle F an adjustable nut F, by means ofwhich the spindle F and its nailclinching and heel-regulating block fare made vertically adjustable, according to the thickness of the heelthat is being made. Above the nut F is made fast on the spindle F acollar F, and between it and the upper end of the nut F is placed ayielding packing or cushion F for the purpose of allowing the block f toyield slightly downward in case the depth of the combined heel-liftscontained within the die E should exceedthe distance between the top ofsaid block f and the upper cutting-edge of the heel-die E.

3 On two opposite sides of the die-carrier E are arranged shear-platesand heel-lift supports E -Ei upon which are placed the heelpieces whichare to be trimmed off to a straight edge for the purpose of butting themagaist similar pieces, and to the frame A are secured the shears orcutting-knives A A opposite to the shear-plates E E, by whicharrangement the heel -blanks are cut and straight-edged during theupward movement of the die-carrier E, as shown in Fig. 1. Above theheel-die is pivoted at a to the rear side of the upper portion of theframe or standard A the horizontally-swinging arm or lever G, which isbent laterally at each extremity to extend round to the front of thestandard, and is provided in one end with a cutterblock and in its otherend with a heel-nailing device, hereinafter to be more fully described.

The pivoted arm G has at one of its ends a vertically-perforated hub G,in which is journaled an internally-screw-threaded sleeve or nut G,having a flange or collar G at its upper end adapted to rest on theupper surface of the hub or hearing G, as shown in detail in Fig. l.

G is the cutter-block, preferably made of wood, which is secured in asuitable manner to the inverted cup-shaped block-holder G", having anupwardly-projeating screw-threaded shank G screwed into the nut G, bywhich arrangement the cutter-block and its holder may be adjustedvertically relative to the cutting-edge of the heel-die E". A setscrew Gseeures the screw-threaded shank G to the nut G after such adjustment ismade.

G is a handle on the hub G for the operator to take hold in swinging theblock G into position above the heel-die E" during the operation ofcutting the heel-blanks.

G is an adjustable stop-screw or projection on the arm G for the purposeof limiting the swinging motion of the said arm in thedirec tion shownby arrow in Fig. 3, which projection is brought in contact with the sideof the standard A when the block G is swung to an operative positionabove the heel-die E", as shown in Figs. 1, 2, and

The opposite end of the pivoted arm G has a vertically-perforated hub orsleeve g, in which is arranged the driver-block holder g which isscrew-threaded in its upper end and there provided with a nut g for thepurpose of vertically adjusting the said driver-block holder relative tothe sleeve g, according to the length of the nails that. are used fornailing the heels. I

g is the driver-block, secured in a suitable manner to the lower end ofthe holder 9', which drivenblock is provided with one or more driversaccording to the number of nails used in nailing each heel.

g is a sleeve surrounding the sleeve g and adapted to slide up and downon the latter. The sleeve 9 is normally held in its lowest positionrelative to the sleeve g by the influence of a spiral spring 9surrounding aguiderod 9 secured in its upper end to the arm G. The lowerend of said spring 9 presses against an earor projection gon the sleeve9, through which car the lower end of the guide'rod g passes loosely, asshown in Fig. 6. Bclowthe sleeve 9 is pivoted on the guide-rod g theperforated loader II, having one or more vertical perforations ll,corresponding in positions to the drivers ll" is a spring-pressedlocking-pi n arranged in a recess on the side of the sleeve g", andadapted to enter a recess II on the loader II when the latter is swunginto operative position below the drivers, and thus causing the saidloader to be held in such position during the nailing operation. Belowthe loader H is pivoted on the guide-rod g the perforated gate ornail-dischargerl, having perforations 1 corresponding in positions tothose of the loader-perforations II. A nut g on thelower end of the rod9 prevents the said gateIand loader H from dropping oft said rod, asshown in Fig. 6. The gate I is limited in its swinging motion on the rod9 relative to the loader H by means of a pair of stop-pins h and h,secured to the under side of said loader, as shown in Figs. 6, 7, and 8,for the purpose of preventing the nails from passing outthrough theloader-perforations until the nailing device has been swung intoposition directly above the heel-die.

I" is a projection or handle on the gate I for the purpose of swingingit against the stop projection h when the loader is to be filled, inwhich position the loader-perforations are covered by the solid portionof the gate I.

The loader is preferably charged with nails by an'attendant during thecutting operation of the heel-blanks, and this is done by swing ing theloader and gate to one side of the sleeve 9 and the nails dropped byhand into the loader-perforations, with the points of the nails restingon the non-perforated part of the gate 1, after which the filled loaderand its gate are swung in position below the drivers, as shown in Fig.6, with the points of the nails still resting on the non-perforatedportion of the gate I.

g is a handle on the sleeve g for the operator to take hold of whenswinging the nailing device into position directly above the heel-dieE".

f is an adjustable stop-screw on the arm G, which is brought in contactwith the side of the standard A when the nailing de vice is swung intooperative position above the heel-die E, and when swung to such ositionthe gate I is brought in contact wit 1 a stationary projection a on thestandard A or guide A, causing the said gate to be swung against thestop-pin h on the loader, thereby causing the gate andloader-perforations to coincide and allowing the nails to rest on top ofthe heel-blank contained within the heeldie E, which when moved upwardby the crank 0, causes the gate and its loader to yield upward by theupward motion of the heelblank and causing the nails to be driventhrough the said heel-blank by means of the stationary drivers g andclinched again st the block f in the bottom of the heel-die E".

A in Figs. 1 and 2 is a forwardly-projecting support at the upper end ofthe frame A, beneath which the nuts G3 and g 011 the cutter-block andnailing device are respectively moved during the dieing-out and nailingoperations of the heel, which support A serves for the purpose ofrelieving the arm G from upward pressure during the dieing-out andnailing operations, and transferring such up-- ward pressure caused bythe upward movement of the heel-die and heel-blank, respectively,against the cutter-block and nailing device directly against thestationary support A on the frame A.

After the heel has been nailed, as above described, it is removed fromwithin the die I, which is accomplished by means of a hand-lever K,pivoted at k to the frame A, and having its inner end adapted to come incontact with a projection or hub K, secured to the spindle F, as shownin Figs. 1, 2, and 5. It will thus be seen that by depressing thehand-lever K the spindle F and the heelsupporting block f will be raisedsufficiently to push the heel upward and out of the heeldie E". As soonas the operator lets go the handle K it is automatically raised to theposition shown in Fig. 1 by the influence of a suitable spring Iallowing the spindle F and heel support f to drop to their original andnormal working positions, as shown in Figs. 1 and 5.

The operation of the invention is as follows: The operator takes a pairof heel-pieces and places them on the shear-supports E E and starts themachine by depressing the treadle D, by which the die-carrier E israised and returned to its normal lowest position, and during the upwardmotion of said die-carrier the heel-pieces held on the parts E E are cutand straight-edged by the action of the stationary blades A A The piecesso out are then butted together and placed on top of the die E". Themachine is then started as before, causing the heel-pieces resting onthe die E to be brought in contact with the under side of the block G bywhich the heel-blanks are cut out to the shape of the die E" and pushedinto said die. This operationis repeated until the requisite number ofheel-lifts have been died out and the die E filled, the upper heelliftbeing made, preferably, to project slightly above the upper edge of thedie. The operator then swings the block G4 out of position and swingsthe nailing device to the position previouslyoecupied by thecutter-block. The said nailing device having in the meantime been loadedwith the requisite number of nails, the operator again starts themachine,

causing the nails to be driven into the heel and, if desired, clinchedagainst the heel-support f. After the heel has been nailed the nailingdevice is swung out of position sufliciently to allow of the expulsionof the heel, which is done by depressing the handle-lever K. After theheel has been removed from the die E the cutter-block is again swunginto position above the die E" for dieing out heel-lifts for theformation of heels to be nailed, and so on.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. In aheel-making machine, the combination, with a standard, avertically-movable die-carrier, and means for reciprocating the latter,of a heel-cutting die mounted on the carrier and having a topcutting-edge, a swinging arm pivoted to the rear side of the standardand having a laterally-bent extremity to extend round to the front ofthe standard and move in a horizontal plane above the heel-cutting die,a cutting-block mounted on the laterally-bent extremity of the arm, andmeans for. vertically adjusting the cuttingblockrelatively to thecutting-edge of the cutting-block, substantially as described.
